Title: Method for detecting leak position of gas
Inventor: NAKANO KAZUNORI
IPC: F17D5/02
Filed: 1991-12-26
Abstract: PURPOSE:To eliminate erroneous judgement caused by that the judgment result of a gas leak position is affected by the individual difference or physical condi tion of a worker because the peak of the concn. of combustible gas is observed at a plurality of places in a conventional method detecting a gas leak position by measuring the concn. of the combustible gas and the worker experientially judges a gas leak position by confirming the smell of the gas. CONSTITUTION:A plurality of measuring places are selected from a gas control part and, by measuring the concns. of the combustible gas to be measured present at the measuring places, a plurality of peak parts where the concn. of the combustible gas locally becomes high are calculated. By measuring the concns. of a smell imparting agent at the measuring places, the high concn. part of the smell imparting agent becoming high in concn. is judged to be a substantial gas leak position.

Abstract: PROBLEM TO BE SOLVED: To reduce the oscillation of a current in the case of current path switching without increasing the number of stages of transistors(TRs) between power wires. SOLUTION: In either of two on/off states of a couple of differential TR switches 22A, 22B, a D flip-flop 26A is used to shift a base potential of a TR buffer circuit 24 to reduce potential fluctuation of one terminal of a constant current source 21 so as to allow a comparator 214 to reduce the oscillation of the current due to a transient response of the constant current source 21 subjecting to feed back control. Furthermore, an oscillation of an emitter coupling point potential at a switching time of a couple of the differential TR switches 22A, 22B is stored in a RAM and a correction waveform is applied to a base of the TR buffer circuit 24 to reduce the current oscillation due to the transient response of the feedback control.

IPC: G06Q50/04
Filed: 1998-12-03
Abstract: PROBLEM TO BE SOLVED: To provide a new rolling order deciding method by which the optimum schedules of heating and rolling are made making a point of grouping rolled stocks having the same heating conditions. SOLUTION: First, heating groups (a)-(e) which can be charged into the same heating furnace in a heating group forming stage 18 and, on the basis of these heating groups, rolling groups 1-7 which can be fed to a rolling mill at the same time in rolling group forming stage are formed in the rolling group forming stage 20. By taking these rolling groups (1)-(7) as a unit, the order of rolling and allotment to a heating furnace are executed.  According to such a method, since the order of rolling and allotment to the heating furnace are selected on the basis of grouping taking the heating conditions into consideration, even when it is required to charge and heat only the slabs of the same heating conditions into the same heating furnace, for example, from problems in quality or the like, the charging order of a rolled stock into the heating furnace and rolling order with a rolling mill are optimally decided so as to obtain excellent rolling efficiency while satisfying such heating conditions by priority.

Title: Water temperature correction system for internal combustion engine and method for the same
Inventor: SEOK JIN-TAE
IPC: F01P11/16
Filed: 1999-12-03
Abstract: PROBLEM TO BE SOLVED: To control operation of an internal combustion engine accurately regardless of influences from outside by judging whether or not value of a cooling water temperature is above a predetermined reference value, and correcting, if YES, the value of water temperature based on a correction control signal so as to feed the corrected value of water temperature into a micro computer. SOLUTION: When water temperature value WT from a water temperature sensor is more than a predetermined set reference value, a micro computer outputs a correction control signal to an interface circuit (S120). The correction control signal amplified by a first amplifier controls a first transistor after reducing its voltage by first and second resistors. The water temperature value WT is corrected as a ratio of partial pressure distributed by a voltage distributor with fifth and sixth registers connected in parallel, and the corrected water temperature value is input in the micro computer.  From then, the micro computer receives the corrected water temperature value (S130), and performs driving control by setting voltage value according to water temperature value based on a memory map table which is a characteristic curve of partial pressure by the fifth and sixth registers with respect to the water temperature (S140), and returns to the initial step (S100).
